Solo training wins on flexibility and focus. You control the pace, the exercises, the rest periods. There's no waiting on other people and no social pressure. For people who train with specific goals — building a particular lift, following a structured hypertrophy program, training for a sport — solo work is usually the better vehicle.
Group training wins on accountability and energy. It's harder to skip a session when five people are expecting you. The group dynamic pushes effort levels most people can't replicate alone. And for beginners especially, having a trainer in the room correcting form and guiding the workout removes a lot of the uncertainty that keeps people from showing up.
The cost difference is significant too. A group PT session at $20 versus a 1-on-1 at $60-80 means more sessions for less money, which for many people produces better results through consistency.
At Adapt Fitness our group classes are capped at 4 people. That keeps it small enough for individual attention while still having the group energy. It also means the timetable fills up — worth booking in advance. We also offer free check-in sessions for members which sit between group PT and full personal training in terms of structure and support.
Our honest recommendation: if you're new or returning after time away, start with a mix. Use group sessions for energy and accountability while building your own programming knowledge on the side.
